Posted October 30, 200816 yr Hello. Does anyone know the stock size for an 84 xs400 maxim main jet size. Ive been trying to dial it in since I bought the bike. It has K&N pod filters. The bike had 2 different main jets when I first pulled it apart.I've had 125,122.5,120 and since I don't have 117.5 ill be putting in 115's tomorrow. Also I can find lots of parts and info on 83 maxims but hardly anything on 84's. Why is that???And before it is suggested I will not be reconnecting the stock air box. Thanks
